flood tides early next week

I’m very new to fly fishing, but plan on wading the flats near Sullivan’s island Mon, Tues, and Wed after work to see if I can get any tailers. I have a few spoon flies, crab flies, and a few that are supposed to resemble shrimp. What shouls I use this time of the year? I’m thinking the crab fly or spoon fly may be my best bet. Any tips or suggestions would be great!
